amphibian : any of a class (Amphibia) of cold-blooded vertebrates (such as frogs, toads, or salamanders) intermediate in many characters between fish and reptiles and having gilled aquatic larvae and air-breathing adults — Webster See also OneLook
Roget’s II (Thesaurus.com), Merriam-Webster Thesaurus, Visuwords
Amphibians are vertebrates that is four-limbed and ectothermic of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are ecological indicators; in recent decades there has been a dramatic decline in amphibian populations for many species. — Wikipedia

Herpetology is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition “herps” (or sometimes “herptiles” or “herpetofauna”) exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. — Wikipedia

- Researchers discover birds with neurotoxin-laden...on March 31, 2023 at 4:06 pm
An expedition into the jungle of New Guinea has resulted in the discovery of two new species of poisonous birds. Genetic changes in these bird species have allowed them to carry a powerful neurotoxin.
- Predatory dinosaurs such as T. rex sported...on March 30, 2023 at 9:21 pm
A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.
- Turtles and crocodiles with unique...on March 28, 2023 at 6:54 pm
New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.
- Certain frogs more sensitive to climate change,...on February 27, 2023 at 6:26 pm
Amphibians worldwide are affected by climate change and potentially one of the most threatened. Biologists found that some species of amphibians are more likely to be sensitive to climate change because they are not protected by state or federal regulations. The team determined that approximately 11 percent of anuran species are sensitive to climate change, but are not currently listed as at-risk either at the state, federal, or international levels.
- New human antibody neutralizes snake neurotoxins...on February 23, 2023 at 6:28 pm
A prototype treatment for snake bite envenoming proves effective against the venom of African and Asian elapid snakes, such as some cobra, mamba, and krait species, new research shows.

- Hope for salamanders? Study recalibrates climate...on March 31, 2023 at 6:22 pm
For tiny salamanders squirming skin-to-soil, big-picture weather patterns may seem as far away as outer space. But for decades, scientists have mostly relied on free-air temperature data at large spatial scales to predict future salamander distributions under climate change. The outlook was dire for the mini ecosystem engineers, suggesting near elimination of habitat in crucial areas.

An expedition into the jungle of New Guinea has resulted in the discovery of two new species of poisonous birds by researchers from the University of Copenhagen. Genetic changes in these bird species have allowed them to carry a powerful neurotoxin.

Humans and other vertebrates (like mammals, birds, fish, reptiles and amphibians) have complex, multi-faceted immune systems that protect us from a constant barrage of bugs and other nasties. But what about insects and other invertebrates?

Ancient 2-meter-long amphibians swam like crocodiles long before true crocodiles existed, according to a study published March 29, 2023, in the open-access journal PLOS ONE by David P. Groenewald of the University of the Witwatersrand, South Africa and colleagues.
- Lizards at US Army installation are stress eating...on March 29, 2023 at 5:00 am
Lizards may be small, with only a single hearing bonelet compared to our three, and without earflaps, but their hearing is typically good. Most lizards can hear frequencies between 100 and 5,000 Hz (although they are most sensitive between 400 and 1,500 Hz), compared to between 20 and 20,000 Hz in humans. So how do lizards react to noise pollution?
